Lies

• Spreads the lie that American schools once taught flat earth. In his efforts to spread this lie, Weiss has committed elder abuse.
• Spreads the lie that Polaris has been seen from the Southern Hemisphere.

Leaky App

DIRTh's app is spectacularly insecure. It's been known to leak user email addresses, coordinates on the globe, and passwords in the clear since October 2024 and is still not fixed as of February 2026.

The app computes distances internally using the Haversine formula. See Image.

Weiss-isms

"Why don't we see any land when we're looking down at the ocean?”

“West is where you are, south is everywhere else.”

About April 8, 2024 Total Solar Eclipse: “Whatever it is that is blocking the sun isn’t in front of it, it’s behind it”

“If refraction were real, somebody should be able to walk down a city block and take a right-hand turn, and if they went far enough, they should refract back out so you could see them on the same avenue”

"All your listeners can see it"

"Spectroscopy needs to be in a container"; an assertion he made while debating Professor Dave.

Antisemitism

David Weiss is a Jew who had a Bar Mitzvah. On May 21, 2025, he hosted a Zoom call where about 80 Rabbis and devout Jews were invited. Dave brought Austin Whitsitt, a Holocaust denier and antisemite, to the call. During the call, one of the participants asked Dave if he would denounce antisemitism. He refused.

In the email thread after the show, Dave requested to be removed from the email thread, but before he left, he was specifically asked to denounce Holocaust denial or antisemitism:

David Weiss, do you denounce Antisemitism?

A simple “yes” will do.

Or any other response including no response is clearly “no”.

He refused to answer, making his position clear.

Knowledge about the model

DITRH claims that people on the globe side are not qualified to talk about the globe for not knowing all the Trivia. So let's make a table about what we know about the globe and what Dave knows about flat earth, to see if he is qualified to talk about flat earth.

Question	Globe	Flat earth
Radius of Earth	6371.0 km	Unknown
How thick is earth	12,742 km	At least 12 km
How fast is it spinning at the equator	Once a day	Not applicable
How fast does the sun move around earth	Not applicable	Unknown
Distance between sun and earth	About 151 million km	Somewhere between "it's in the clouds" and a few thousand km.
What do we observe in the sky	Planets, stars, moons, asteroids	Dave: The only thing that we can say about the sky is that anything that we see in the sky is that they're lights.
What is the sun/star	Britannica: Any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources.	Dave: I don't believe that the sun and the moon that we see are physical. I believe there is a physical sun and moon, but I think it's more of a projection into our what I call our sky screen.
What is the moon	Britannica: Moon, Earth’s sole natural satellite and nearest large celestial body.	Dave: I think it's a plasma.

According to his own standard he is not qualified to talk about earth's shape.

Chicago Skyline

Dave: They don't talk about, hey, across Lake Michigan, I can see Chicago 57 miles away.

Apollo The Original: Mhm.

Dave: Right. And I can't see the very very bottom of the lowest buildings, but I can see the rest. Well, the top of the tallest building should be a couple hundred feet below the curve, but we can see the whole city.

Dark Star analysed the photo and showed there is a lot more missing than just the bottom of the lowest buildings.

The radius has been debunked

Dave: The radius the line from the center of the earth to the surface. It's three, nine, five, nine, 3,959 miles. That's been debunked because the radius tells us the circumference. The radius tells us how much curvature there is over a certain distance. And we can see things far beyond that physical limitation of a globe. So the radius has been debunked. What does that mean? That means that all of the planetary distances, the moon, the sizes, that's been debunked. Space travel has been debunked. Our solar system's been debunked. Everything has been debunked when the radius is debunked. The Earth is flat and it's provably so.

As the previous example already showed, he ignores the atmosphere.

Antarctica

Mountains and dome

Dave: There's mountains in Antarctica. They call them uh there I mean the names of the mountains are very weird. But um there's supposedly mountains there higher than Everest, but they don't tell us about that.

Apollo The Original: Then How do you know that?

Dave: Well, this is information that we have from some explorers from from old encyclopedias. The encyclopedia from 1958 says at 80 degree 80 or 85 degrees I forget 80 degrees 80 degrees south which is way south farther than any one is allowed to go and and independently they say that there's a domed ceiling at 13,000 ft.

The highest peak in Antarctica is the Vinson Massif at a height of 4,892 m (16,050 ft), which is significantly smaller than Mount Everest.

The encyclopedia American does talk about a dome, but in this context it's a geological structure. It should be obvious to anyone that no one would measure the height of a dome near its edge, but always at its highest point.

Apollo The Original even checks it himself with Dave present.

Antarctic Treaty

Dave: Um what's out there? There's no free and independent exploration. All the countries in the world that are waring with each other, they all agree nobody can go to Antarctica. And that's a fact. No. Well, you can't go.

They'll say, "Yes, you can. You can buy a trip. All these people go. Thousands of people go."

Not thousands. You know, some people go every year, but um they only take you to the very tip of Antarctica. the very, you know, that little spit that comes out near South America. They take you to a little island there. Um, and that that's all they let you uh see. They only take you to um I can share this with you. Let me let me just let me do that. So, I'm going to show you the bases. So, they only take you there. There's two little islands that they take you to. And one of them is called Deception Island, and the other one's called, I believe it's Rothschild Island.

First, the Antarctic Treaty literally tells people that it encourages freedom of scientific exploration and studies. Second, The Final Experiment showed that you can book a trip inland.

TFE

Apollo The Original: Okay, let's go. Uh, Antarctica. Okay, so you've never been to Antarctica?

Dave: No, I was invited to go a free trip. Um, but it was based on a false premise by some very evil um not honest people. And I said, I'm not interested. Right? Because they were going to there there was a big deception there back in 2024 where they took some um people. It was supposed to designed for me because I was been waking up too many people with my app with uh you know with all the interviews I'm doing and they wanted to take me down. But I immediately I have a very good sense um of evil. I just met you.

Apollo The Original: Yes, sir.

Dave: I can tell you're a good guy. I can tell before you open your mouth. Right. I I can tell. I got an email and I felt literally demonic forces. Right. And it was like we're doing this experiment. I'm like what's the experiment? You're looking at the sun. like, "Wait, what?" And then uh a second email and I replied back, "I don't deal with demons. Don't ever contact me again." And uh and it turned into a whole ordeal. But they ended up taking down the the biggest anti-flatearh paid agents to Antarctica, and they were the first ones ever to film a 24-hour sun down there. No institution, no ex no explorers, nobody. But these guys filmed it for the first time. It's crazy.

TFE was not designed for Dave. He just got the most votes to be taken to Antarctica.

Furthermore the 24h sun had been filmed multiple times before TFE. For example Anthony Powell has multiple videos filming the 24h sun years before TFE.

If Dave actually could feel what he calls evil forces, he would not have joined the Conspira-cast podcast.

After TFE he changed his stance from the 24h sun proves that earth can't be flat:

Dave before TFE: One of the arguments that people give is on a flat Earth you can't have a 24-hour Sun a midnight sun in Antarctica and I totally agree, but there is no Midnight Sun in Antarctica.

To, it proves nothing:

Dave after TFE: Is it going to prove the shape of the earth to see the 24hour sun? But what does that prove that? So, if you think that the 24-hour sun in Antarctica proves the shape of the Earth, you now have to prove first that the Earth is a ball, well, the radius has been falsified. Two, you have to prove that gas violates uh natural law that it can exist in a vacuum, right?

Population

Dave: You could take the population of the world and everybody can live in Texas and half of Texas would be empty, right? So, it's incredible how much space and that's with the number they give us 8 billion people. I think there's two billion people maybe.

Apollo The Original: So, they say that uh population of China's population.

Dave: Yeah. So, that that's this is good.

Apollo The Original: So, I did this exercise a couple of years ago.

Dave: Yeah. But while you're looking that up,

Apollo The Original: 1.4 Mhm.

Dave: 1.4 billion. Yes. Right. So they went from um well they went from 500 million to 1.25 billion in I think it was 20 years something like that. So that would require every couple to have five children. This happened during their one child rule.

China's population went from about 500 million to about 1.4 billion in around 60 years, 3 times longer than Dave claims.

As evidence they use the population of the 50 largest cities in China, which sum up to about 337 million people.

The 50 largest cities of China are along the coast. So he is essentially ignoring most of the country.

Seasons

DITRH explains how seasons are supposed to work, completely ignoring South of the equator.

Below is a selection of how the the illuminated part of earth would like on Dave's flat earth model, animated by Jos Leys.

As most people can see, the light pattern makes no sense. Light would need to behave very differently depending on the location of the sun over a flat earth.

If we take for example the December solstice and add the directions where the sun is observed for different locations. Animation done by Jos Leys.

On the flat earth, the sun would be all over the place. On the globe on the other hand, the sun is larger than earth and in just one location.

Flatearthers always use the straw man that seasons are caused by the distance to the sun on the globe. That's not true. It's the angle to the sun that causes the seasons. That's why we can have winter in the north, when earth is actually closest to the sun.

Moon

Cold moonlight

Dave: So but the moon is clearly a light in the sky and and you can actually measure moonlight um that it it um is cold. The moonlight is cold.

MCToon demonstrated that the moonlight is not cold. In fact, cold light is physically impossible. Light transports energy, and energy transfers heat. To cool something down, you need to remove energy.

Moon brightness

Dave claims that you should be blinded when near the moon.

Dave: So, RMS 2, when they flew right next to the moon, it would be super bright. It it should be it should be the we did the math. When you're 100 miles from the moon, the moon should appear brighter than we see the sun from Earth. Impossible to watch it.

He completely ignores that when you get closer to the moon, you also see less of its surface area. Furthermore, earth is significantly brighter than the moon, as it's more reflective than the moon, especially on the ocean and ice. Yet somehow that's not a problem. Dave McKeegan made a video explaining it.
